Description

Disc eject method

technical field

The invention relates to a device and method for ejecting optical discs, in particular to a device and method for ejecting small-sized optical discs from a slot-in optical disc drive.

Background technique

The slot-in optical disc drive uses several guide rods to form an advance and retreat mechanism. When a disc is inserted into the entrance and exit, the disc can be automatically sucked in by the advance and retreat mechanism for reading and writing. When the film is unloaded, the disc is automatically sent to the entrance and exit by the advancing and unwinding mechanism, which is convenient for the disc to be taken away or replaced.

As shown in FIG. 1 , it is the background technology of China Taiwan Publication No. 200811834 patent filed by the applicant. The background technology is a slot-in optical disc drive 1 that can advance and retreat two sizes of discs, 12 cm and 8 cm. A sliding member 3 is moved by a transmission unit 2 to link a disc advance lever 4, and a disc C of a small size of 8 cm can be dialed in. The sliding part 3 is also connected with a link mechanism 5 to rotate the ejection lever 6 to push out the small-sized optical disc C, so that the small-sized optical disc C exits the suction-type optical disc drive 1 along the connecting rod 7 until part of the entrance 8 is exposed. , easy to remove or replace.

However, the mechanism of the slot-in optical disc drive 1 is based on the commonly used 12cm large-size optical discs for advancing and retreating, so that when the small-sized optical disc C retreats to the entrance and exit 8, only a small part exposes the entrance and exit 8, and most of them still stay in the slot-in optical disc. In the machine 1, especially the central hole 9 still does not expose the entrance and exit 8, resulting in a poor force point for taking, and it is inconvenient to take the small-sized optical disc C. Therefore, there are still problems to be solved urgently in the disc ejection device and method of the slot-in disc player 1 in the background art.

Contents of the invention

The object of the present invention is to provide a disc ejecting device. By setting a support block on the disc ejection lever, the distance from which the disc ejection lever pushes out the small-size disc is increased, so that the center of the small-size disc exceeds the contact of the advance lever. A predetermined distance from the end, in order to push out the small-sized optical disk by exerting force on the end of the film-advancing lever.

Another object of the present invention is to provide a method for ejecting an optical disc. After the center of the small-sized optical disc is withdrawn beyond the predetermined distance from the end of the film-advancing lever, the advancing and retreating mechanism is continuously idling to drive the film-advancing dial. The rod then pushes out the small-sized disc to expose the central hole for easy access.

In order to achieve the purpose of the aforementioned invention, in the disc ejection device of the present invention, a support block is provided at the contact end of the ejection lever of the suction-type optical disc drive, and the support block protrudes from the contact end and extends outward along the long axis of the ejection lever. out of the contact end, so that the film ejection lever pushes out the center of the small-sized optical disc, and exceeds the predetermined distance from the contact end of the film advance lever.

In the disc ejection method of the present invention, first start the ejection, check that the ejection of the small-sized optical disc is ejected, and continue to check that the ejection lever returns to the initial position. Once the ejection lever returns to the initial position, the actual exit For the small-sized optical disc, the center of the small-sized optical disc is pushed out for a predetermined distance, and then the idling advance and retreat strokes are continuously performed again to further push out the small-sized optical disc.

Detailed ways

In order to achieve the above object, the present invention adopts the technical means and its effects, hereby give preferred embodiments, and illustrate as follows in conjunction with the accompanying drawings.

Please refer to FIG. 2 , FIG. 3 and FIG. 4 , which illustrate the progress of the slot-in optical disc drive 10 provided with the disc ejecting device of the present invention. The mechanism and process of the slot-in optical disc drive 10 advancing and retreating large and small optical discs are applied for in the aforementioned background technology, and are not the technical features of the present invention. For detailed technical content, please refer to the background technology and will not repeat them. The following is only a brief description of the aforementioned background technology related to the advance and unwind process of the small-sized optical disc C of the present invention. As shown in FIG. 2 , when a small-sized optical disc C is inserted into the slot-in optical disc drive 10 , one side of the optical disc C will move along the flange 12 of the connecting rod 11 and enter the slot-in optical disc drive 10 . Since the width from the flange 12 to the film advance lever 13 is slightly smaller than the diameter of the optical disc C, the inserted optical disc C can only slightly push away the piece end 14 of the film advance lever 13 to the side, and cannot effectively rotate the transmission rod 15 to drive The guide pin 16 touches the retaining edge 17 and rotates the buckle lock 18, so that the buckle pin 19 is still stuck in the buckle groove 20, so that the connecting rod 11 cannot slide sideways along the first chute 21 and the second chute 22. At the same time, the first contact pin 23 on the contact rod 11 cannot be separated from the first sensing switch 24, and continues to maintain the "on" state.

As shown in FIG. 3 , when the optical disc C continues to be inserted, the disc ejection lever 25 that is more protruded will be pushed backward to rotate the disc ejection lever 25 when it penetrates into the periphery of the optical disc C. The film ejection lever 25 moves the first connecting rod 27 through the fixed pin 26, so that the second contact pin 28 on it is separated from the second sensing switch 29, and it is in the state of "off", and it is judged that the small-sized optical disc C is advancing , start the transmission motor 30 simultaneously. The transmission motor 30 rotates the gear set 31 to drive the slider 32 to move forward.

As shown in Figure 4, the slide plate 33 fixed on the slider 32 moves forward, and the guide groove 34 on the slide plate 33 rotates the transmission rod 15 to drive the film advance lever 13 to dial in the optical disc C, and the optical disc C continues Push back the sheet driving lever 25 and the positioning rod 35. Simultaneously, the slider 32 drives the second connecting rod 37 through the chute 36, and the first connecting rod 27 is linked to rotate the film-removing lever 25 backwards, and cooperates with the positioning rod 35 to guide the optical disc C to align with the spindle motor 38 and move backward, so that the optical disc Slice C goes into position. The sliding part 32 pushes the sliding pin 39, raises the core 40, uses the spindle motor 38 to clamp the center hole 41 of the disc C, and the sliding part 32 continues to move the film advance lever 13, the film ejection lever 25 and the positioning rod 35 to separate from the disc C until the rear end of the slider 32 releases the third sensing switch 42, which is in the "off" state, and the transmission motor 30 is turned off, so as to complete the positioning of the optical disc C.

The process of ejecting the optical disc C from the slot-in optical disc drive 10 is just opposite to the aforementioned process of advancing the disc. Firstly, the transmission motor 30 is started in reverse, and the rotating gear set 31 drives the sliding member 32 to move backward. The sliding member 32 moved backward drives the slide plate 33 to rotate the transmission rod 15, and drives the sheet advancing lever 13 outward. At the same time, the slider 32 uses the chute 36 to drive the second connecting rod 37 , and in conjunction with the first connecting rod 27 to rotate the ejection lever 25 forward to push out the optical disc C. The rear end of the sliding member 32 first touches the third sensing switch 42 and returns to the "on" state. The slider 32 continues to move backward, drives the second connecting rod 37 through the chute 36, and drives the first connecting rod 27 to rotate the moving rod 25 forward, as shown in Figure 2, the second connecting rod 27 on the first connecting rod 27 The contact pin 28 touches the second sensing switch 29 again, and is in the “OFF” state, and the disc ejection lever 25 linked by the slider 32 pushes the optical disc C to partially expose the entrance 44 .

The present invention mainly utilizes the advance and retreat sheet mechanism of the aforementioned background technology, and a support block 50 is set at the contact end 45 of the sheet retraction lever 25, and the support block 50 stretches out from the contact end 45, and can be moved along the long axis of the sheet retraction lever 25. Stretch, increase the distance that the ejection lever 25 pushes out the optical disc C, to constitute the optical disc ejection device of the present invention. However, because the support block 50 is limited by the internal rotation space of the slot-in optical disc drive 10, and to avoid affecting the ejection lever 25 to guide the optical disc C to automatically align with the spindle motor 38, the extension distance of the support block 50 is limited, so it cannot be The optical disc C is pushed out from the entrance 44 for a proper distance. The protruding distance of the support block 50 in the present invention is mainly to ensure that the second contact pin 28 on the first connecting rod 27 touches the second sensing switch 29 again, and when it is in the "off" state, the ejection lever 25 returns to the initial state. The position, the angle of forward rotation can push the center of the small-sized optical disc C (as shown by the middle line K in FIG. 2 ) beyond a predetermined distance D beyond the piece end 14 of the film advance lever 13 (as shown by the middle line L in FIG. 2 ). , the larger the predetermined distance D, the better, the present embodiment exceeds the radius of the central hole 41, but at least greater than 1/2 of the radius of the central hole 41, so as to avoid the force point where the contact end 14 contacts the optical disc C and is too close to the optical disc C The center of the disc will cause the disc to jam when it is dialed in again.

The disc ejection method of the present invention, when the second sensing switch 29 is in the "OFF" state again, confirm that the disc ejection lever 25 returns to the initial position, because it has been judged that the slot-in disc drive 10 is a small-sized disc C , that is, the transmission motor 30 is forwardly rotated, and the slider 32 will continue to move toward the front of the slot-in optical disk drive 10 . The sliding part 32 drives the sliding plate 33 to rotate the transmission rod 15, and drives the film advance lever 13 to rotate in the direction of dialing in the optical disc C. Since it has been ensured that the center of the optical disc C exceeds the contact end 14 of the film advance lever 13 by a predetermined distance D, the film advance lever 13 cannot be moved into the optical disc C, but pushes the rear peripheral edge of the optical disc C to push out the optical disc C. As shown in FIG. 5 , it is the state of re-feeding the film in an empty machine according to the present invention. When there is no disc C in the slot-in optical disc drive 10, the slider 32 moves forward to release the third sensing switch 42, and at the same time drives the film advance lever 13 and the film eject lever 25 to move in the film advance direction, as described above. During the film process, carry out an empty machine feed rotation again, allowing the film advance lever 13 to push the rear peripheral edge of the optical disc C, and under the limit of the connecting rod 11, the optical disc C is pushed out of the entrance and exit 44 more. The central hole 41 of the optical disk C is half exposed to the entrance 44 .

As shown in FIG. 6 , the present invention exits the CD state. The slider 32 moves forward until the third sensing switch 42 is released, then reverses the transmission motor 30, and moves the slider 32 backward, as in the aforementioned film unwinding process, drives the film advancing lever 13 and the film ejecting lever 25, and then proceeds Once the empty machine unwinds and rotates until the rear end of the slider 32 touches the fourth sensing switch 43, the drive motor 30 is rotated forward to drive the slider 32 to move forward, and after releasing the fourth sensing switch 43, the drive motor 30 is turned off , to complete the entire unwinding process. The advancing film driving lever 13 and the film withdrawing driving lever 25 of forward rotation can no longer touch the optical disk C, and the central hole 41 of the optical disk C is half exposed and stays at the entrance and exit 44. Take the disc C.

As shown in Figure 7, it is the detailed steps of the disc ejection method of the present invention. Firstly, in step S1, start the slot-in optical disc drive to eject the disc, and enter step S2 to check whether the ejected disc is a small-sized disc? If it is not a small-sized optical disc, enter step S3 to perform an unloading process only once, and then enter step S7 to complete the unloading process; if it is a small-sized optical disc, then enter step S4 to perform unloading, and then enter step S5 to continuously check the unloading process The driving lever returns to the initial position again, if the film ejection lever returns to the initial position, then enter step S6 to continuously carry out the film advance-film ejection stroke, and finally enter step S7 to end the film ejection stroke.

The optical disc ejecting device of the present invention can set a supporting block on the disc ejection lever, and the extension length increases the distance from which the disc ejection lever pushes out the small-sized optical disc, so that the center of the small-sized optical disc exceeds the contact end of the disc advance lever The predetermined distance makes it easy for the connecting end of the film advance lever to exert force on the small-sized optical disc, so as to prevent the optical disc from being jammed. Using the method for ejecting the optical disk of the present invention, when the small-sized optical disk is ejected, the stroke of ejection-advance-ejection is continued, that is, after actually ensuring that the small-sized optical disk is withdrawn from a predetermined distance without jamming, Continuously perform one advance and retreat stroke of the idling advance and retreat mechanism, drive the advance lever and then push out the small-size disc, so that the central hole is half exposed to the entrance and exit of the suction-type disc drive, and the small-size disc is continuously ejected at one time, so that it is convenient to take Pick.

The above is only used to illustrate the preferred embodiments of the present invention, the scope of the present invention is not limited to these preferred embodiments, any changes made according to the present invention, without departing from the spirit of the present invention, All belong to the scope of the patent application of the present invention.
